Nephrogenic diabetes insipidus (NDI) is caused by the inability of the renal collecting ducts to absorb water in response to antidiuretic hormone (ADH), also known as arginine vasopressin (AVP; 192340). Approximately 90% of patients are males with the X-linked recessive form (type I; NDI1), which is caused by a defect in the vasopressin V2 receptor in renal collecting duct cells. The remaining 10% of patients have autosomal NDI (type II; NDI2, 125800), which is caused by mutations in the gene encoding the aquaporin-2 water channel (AQP2; 107777) on chromosome 12q13 (Morello and Bichet, 2001). Neurogenic, or central, diabetes insipidus (125700) is caused by mutation in the gene encoding arginine vasopressin, located on 20p13.  http://www.omim.org/entry/304800

Nephrogenic diabetes insipidus should not be confused with diabetes mellitus, which is much more common. Diabetes mellitus is characterized by high blood sugar (glucose) levels resulting from a shortage of the hormone insulin or an insensitivity to this hormone. Although nephrogenic diabetes insipidus and diabetes mellitus have some features in common, they are separate disorders with different causes.

Infants with hereditary nephrogenic diabetes insipidus may eat poorly and fail to gain weight and grow at the expected rate (failure to thrive). They may also be irritable and experience fevers, diarrhea, and vomiting. Recurrent episodes of dehydration can lead to slow growth and delayed development. If the condition is not well-managed, over time it can damage the bladder and kidneys leading to pain, infections, and kidney failure. With appropriate treatment, affected individuals usually have few complications and a normal lifespan.

Nephrogenic diabetes insipidus can be either acquired or hereditary. The acquired form is brought on by certain drugs and chronic diseases and can occur at any time during life. The hereditary form is caused by genetic mutations, and its signs and symptoms usually become apparent within the first few months of life.

Nephrogenic diabetes insipidus is a disorder of water balance. The body normally balances fluid intake with the excretion of fluid in urine. However, people with nephrogenic diabetes insipidus produce too much urine (polyuria), which causes them to be excessively thirsty (polydipsia). Affected individuals can quickly become dehydrated if they do not drink enough water, especially in hot weather or when they are sick.  https://medlineplus.gov/genetics/condition/nephrogenic-diabetes-insipidus
